tron transport rate. Seedlings grown under the low light intensity exhibited higher photosynthetic rates and compensation irradiance, and displayed higher photosyn-thetic pigment contents and light absorption than seedlings grown under high light intensity, providing strong evidence of photosynthetic acclimation to low light. How-ever, the ...

Summary A new mechanistic model of the photosynthesis–light response is developed based on pho- tosynthetic electron transport via photosystem II (PSII) to speciﬁcally describe light-harvesting characteristics and associated biophysical parameters of photosynthetic ...

How Light Intensity Affects Photosynthetic Rate
photosynthesis. The effect of light intensity followed a Michealis-Menten curve where increases in light intensity corresponded to increases in oxygen production until a peak in oxygen production occurred at a light intensity of 6000 lux. From this, we suspect that E. canadensis has an optimal photosynthetic rate at light intensities of 6000 ...

B. LIGHT INTENSITY AND PHOTOSYNTHETIC RATE When chlorophyll molecules are exposed to light energy, carbon dioxide and water can be utilized to form sugar and oxygen respectively. Since plants do not utilize the colors of the visible light spectrum equally, photosynthetic rates could be altered based upon the intensity of light. In general, if ...

and the rate of bubbling can serve as an indication of the rate of photosynthesis. When the light intensity is increased, the rate of bubble production should increase. Decrease the light intensity and the rate of bubbling should decrease. Remove the light source altogether, or move it to a distance beyond which the energy levels are to small for
